Phoenix Contact MCR-S50/U/I-0/SW 2808954 current transducer 300V 50A, 20-30VDC, relay and optocoupler outputs, 0-10V and 0-20mA, mounting slightly damaged

Current transducer is often referred as a current transformer. This unit can basically sense how much current is going through your wire. In addition to this basic current sensing feature you can set an alarm threshold, which triggers the output.

  • 0...20mA
• Output threshold adjustment:
  • Between 0...100% of the measurement range
• Max wire diameter which goes through:
  • 8mm
• Method of current measurement:
  • Indirect (most likely Hall sensor/transformer)
